Updating the kernel on-line

Hi,

Is there a way so I can update the kernel when the system is still functionning and then reboot to make the change take effect (like what we do for Linux)?

Warm Regards

    You can use u-boot.

    But actually, you don&#39;t need to reboot , unless your nios2 hang.

    If you are developing application, you can terminate it with "kill"....etc.

    Just update the apps on nfs server, then run the new one.

    If you are developing kernel driver, use module load/unload.

    The module file can be on the nfs server, too.

    In summary, you can use Ethernet to download

    1. kernel image via uboot and tftp

    2. apps via nfs

    3. kernel module via nfs
